Abstract:
BACKGROUND: Lipoprotein (a) [Lp(a)] contains apolipoprotein(a), which is a structural homologue of plasminogen and competes with it for binding sites. It also acts by increasing plasminogen activator inhibitor-1 expression. The objective of this study was to evaluate the relationship between Lp(a) levels and restenosis rate after successful coronary stent placement. METHODS: The study included 306 patients who underwent coronary stent placement and follow-up coronary angiogram at Chonnam National University Hospital from August 1996 to June 2000. Restenosis rate was analyzed according to the level of Lp(a); Group I with high Lp(a) (n=7, Lp(a) 36 mg/dL, 58.98.8 years, female: 35.1%) and Group II with low Lp(a) (n=29, Lp(a) < 36 mg/dL, 57.79.8 years, female: 18.8%). RESULTS: 1) There was no significant differences in risk factors of atherosclerosis, clinical diagnosis, the number of involved coronary artery, left ventricular function, angiographic lesion characteristics by American College of Cardiology/American Heart Association clasification and Thrombolysis In Myocardial Infarction flow in two groups. 2) Angiographic restenosis rates were not different between two groups (group I : 33.8%, group II : 35.4%). CONCLUSION: Plasma Lp(a) levels are not related with the angiographic restenosis rate after coronary stent placement.
